Letters Patent No. 96,57 5, dated November 9, 1869.

The Schedule referred. to in these Letters Patent and part of Ithe same.

thereof, referencekbeing had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a top view,

Figure 2, a side View,

Figure 3,21. top view, showing change of position from the plow-beam, and

Figure 4,' a similar view, showing cbangetoward the beam.

My improvements relate to that class of coulters which lis usually called .caster-rolling...coulters; and consists in providing an arm or pendant, having a curved or angular back, with a side cylindrical bearing, to-receive the shaft cfa fork or arms, which hold the Coulter-wheel, so that by reason of such side bearing and the curved or angular back of the pendant, the position of the coulter, relative to theplow, may be easily changed, and adapted to the plow, by bringing the conlter nearer to the plow-beam, or by carrying it further cti, in providing the bottom of such side bearing with a stop, to limit the moafements of the Coulter-wheel, and in the several combinations hereinafter set forth and claimed as new.

To enable 'others skilled in the art to ,make and use my improvements, I will Idescribe. their .construction and operation.

A represents a section ofthe beam of any ordinary plow.

B represents an arm or pendant, 'attached thereto by a clamp or clip, F G, on the landside.

This arm or pendant is usually cast, but may be made of plate-metal, or other suitable material, and has its side next to the vbeam convex, as shown, or it may have a ridge in the middle, or be made angular on the back, if desired.

The bearing C is usually made a part of the arm B, and located at the side thereof, as shown.

The shaft H of the fork E, passes through this bearing, and is held i'n place by means of a pin and a cap or washer, c, at the top.

or lower end of the cylinder lor bearing are, that the top can be closed by a close-fitting cap, or washer, so as to-keep the dirt outof it; and as there is a tendency to twist the shank H, or considerable torsion applied to it, by reason of the angle of the fork E, the shank can be made much lighter when the stop is placed at the bottom than it can be when placed at the top, as the stop is located at or near thepoint of the strain. y

'I am aware that the upper ends of straight shanks or forks, holding the wheel, in coulters which were not o'f the caster or swivel kind, have heretofore been pro- `il'ided with a' curved back, so as t0 change the course of the coulter, and thereby guide the plow so that it will out a wider or narrower furrow; but this old device does not and cannot change the position of the `coulter-wheel, so as to .bring it towardorcarry it from the plow, for the reason that `the axis of the coulterwheel is always in the same place, and turning such shank only changes the direction ofthe wheel, without changing theposition, while'in my device the conlter-wheeldoes not 'and cannot act as a guide to the plow, as it turns freely on,l the shaft H, and

changing by the curved arm or Vpendant simply 4 l by means of wedges driven between it and the'plowbeam. The, use of wedges,l which' are inconvenient and uncertain, is avoided by my invention, and a ready and certain means for adjustment furnished, for by letting out the screwnut d of the clip or clamp, and screwing down'c, as shown at iig/3, the conlter is car.- ried from the beam, and by reversing the movement of these screws, it is drawn toward the beam, asi shown at iig. 4, and thereby adjusted to the location or angle of the beam to which it is attached. y

It will readily be seen, that vthese results are obtained by placing the. bearing C on the 'side of the pendant or arm B, inv connection with .the curved or aligular back thereof, and the clamp. l

The clamp is made of aA bent bar, F, and a crossbar, G, connected by the screws d and 1e, and is at tache-cl -to-the beam of a plow, as show n.

Having'thus fully described my invention, t

jWhat -I vclaim as new, and vdesire to secure by Letterslateut,l is- 1. The ann,- or` pendant B, having a. curved or anguiar bgok, and a. cylinderpr bearing, G, on the side thereof, 'in 4combination with a bent fork, E H, substantially as and for the purposes specified.

2. The combination and arrangement of the adjustable clamp F G, with the beam A, arm B, when provided with a curved or angular back, and'a side bem'ing, C, stop 'a b, bent wheel-fork E, and wheel D, all constructed and operating substantially as specified.v
